What is the minimum height for a building’s sewer discharge above the ground?

The minimum height for a building’s sewer discharge above the ground is typically set at 12 inches. This requirement is crucial for a number of reasons, including preventing backflow and ensuring that sewer lines remain operational and free from obstructions. By establishing a standard height, it helps to minimize the risk of flooding or overflow from heavy rainfall or other water sources. A discharge positioned too low can lead to issues with debris accumulation, which could compromise the sewer system's effectiveness. Adhering to this minimum requirement enhances overall sanitation and public health by ensuring proper drainage away from the building.
